Fuel supply device for a motor vehicle

Abstract

The fuel supply system has a fuel tank, a cup-shaped storage container in the fuel tank with a feed unit disposed in the storage container operable to pump fuel out of the storage container to an internal combustion engine ( 10 ) of the motor vehicle. A filter surrounds the feed unit over at least part of its circumference is disposed in the storage container, through which filter the fuel pumped by the feed unit to the engine flows. The filter is disposed in the storage container next to the feed unit, is embodied with a crescent-shaped curved cross section, and surrounds the feed unit over part of its circumference. The filter has a filter insert folded in star-shaped fashion.

     6. The fuel supply system of  claim 5 , wherein the filter ( 24 ) comprises a housing ( 26 ) secured to the storage container ( 14 ). 
   
   
     7. The fuel supply system of  claim 5 , wherein the fuel tank ( 12 ) has an opening ( 13 ), through which the storage container ( 14 ) can be inserted into it; wherein the opening ( 13 ) is closed with a closure element ( 52 ); and wherein the filter ( 24 ) has a housing ( 26 ) that is secured to the closure element ( 52 ). 
   
   
     8. The fuel supply system of  claim 1 , wherein the filter ( 24 ) surrounds the feed unit ( 16 ) over an angle between approximately 50° and 90°. 
   
   
     9. The fuel supply system of  claim 8 , wherein the filter ( 24 ) comprises a housing ( 26 ) secured to the storage container ( 14 ). 
   
   
     10. The fuel supply system of  claim 8 , wherein the fuel tank ( 12 ) has an opening ( 13 ), through which the storage container ( 14 ) can be inserted into it; wherein the opening ( 13 ) is closed with a closure element ( 52 ); and wherein the filter ( 24 ) has a housing ( 26 ) that is secured to the closure element ( 52 ). 
   
   
     11. The fuel supply system of  claim 1 , wherein the fuel tank ( 12 ) has an opening ( 13 ), through which the storage container ( 14 ) can be inserted into it; wherein the opening ( 13 ) is closed with a closure element ( 52 ); and wherein the filter ( 24 ) has a housing ( 26 ) that is secured to the closure element ( 52 ). 
   
   
     12. The fuel supply system of  claim 11 , wherein the housing ( 26 ) of the filter ( 24 ) is secured to the closure element ( 52 ) by means of an adhesive connection or welded connection. 
   
   
     13. The fuel supply system of  claim 11 , wherein the closure element ( 52 ), on its inside pointing into the interior of the fuel tank ( 12 ), has an annular indentation ( 38 ), into which a filter insert ( 28 ) of the filter ( 24 ) is tightly inserted. 
   
   
     14. The fuel supply system of  claim 13 , wherein the housing ( 26 ) of the filter ( 24 ) is secured to the closure element ( 52 ) by means of an adhesive connection or welded connection. 
   
   
     15. The fuel supply system of  claim 13 , wherein the filter insert ( 28 ) is secured in the indentation ( 38 ) by means of adhesive ( 40 ). 
   
   
     16. The fuel supply system of  claim 15 , wherein the housing ( 26 ) of the filter ( 24 ) is secured to the closure element ( 52 ) by means of an adhesive connection or welded connection.
